25 days ago i gave oral sex to a girl unprotected, and had protected sex with a condom. ive since been worried about HIV. 11 days ago i woke up with a really sore throat, and was sniffing/coughing a lot of mucus. the cough/sore throat has remained since, and its always worse in the mornings. however in the last few days the sore throat has become more focused and feels like its quite low in my throat, almost at the top of my voice box. it feels like quite a concentrated pain when i make a deep swallow. I dont have a cough in that i feel like i need to cough, but i cough just to try and clear my throat. For the first week or so of my sore throat, it almost felt like there was mucus stuck between my nose and throat the whole time, and i couldnt sniff it out. I dont have a fever or runny nose, and have no other real symptoms, although have felt a bit run down. the pain in my throat is now really sore, and it doesnt seem to be improving.
I typed in these symptoms to google and it kept telling me it could be HIV seroconversion.
I got a HIV test 13 days after it happened and it tested negative, but i heard it takes longer than 13 days for it to show positive. do you think i should be worried.
